The Zerus System is a planetary system set at the heart of the Milky Way Galaxy. Featuring the planet of Zerus, the system was graced by the xel'naga and later on, the behemoths. The latter were assimilated by the Zerg Swarm, which then attacked the xel'naga.[1]

The Zerus System lies in the Theta quadrant.[2]
